CVE-2026-36763
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA stored cross-site scripting (XSS) vulnerability in the /api/blade-desk/notice/submit endpoint of SpringBlade v4.8.0 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted input into the content parameter.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStored XSS vulnerability in SpringBlade v4.8.0 allows attackers to inject malicious JavaScript or HTML into the content parameter of the /api/blade-desk/notice/submit endpoint. The injected payload is stored in the backend and executes when other users view the notice.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SpringBlade installation and versionLocate the SpringBlade deployment and check the version metadata (pom.xml, build.gradle, application properties, or deployment descriptors) to confirm version 4.8.0 is runningAffected if The installed SpringBlade version is exactly 4.8.0
-
Verify blade-desk module is enabledCheck the application configuration or module list to confirm the blade-desk module is loaded and activeAffected if The blade-desk module is enabled in the deployment
-
Confirm notice submit endpoint accessibilityVerify the /api/blade-desk/notice/submit endpoint is exposed and accessible in the running environment (check API gateway config, security filters, or test with a read-only request)Affected if The endpoint is accessible without additional authorization checks or the attacker has valid credentials to access it
-
Inspect existing notice records for suspicious contentQuery the notice storage (database table for desk notices) to examine the content field for any non-printable characters, script tags, or HTML markup that may indicate injected payloadsAffected if There are notice records in the database containing script tags, event handlers, or HTML elements in the content field that were not authored by legitimate administrators
You are affected if running SpringBlade version 4.8.0 with the blade-desk module enabled and the notice submit endpoint is accessible to the attacker.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement input validation to sanitize/filter malicious payloads on the content parameter, and apply output encoding when notices are rendered to prevent script execution.
